Hi, i have checked the size of Mailbox store database priv1.edb that is 19.8 GB and the public store database pub1.ebd that is only 67 MB. and i have already extended the size of my Exchange server by following the article http://support.microsoft.com/kb/912375. And i have done same 2 entries in specified location. Then why is only Public Folder Store is dismounting again and again? Please suggest. Regards, Rashid Ali

What's the reason given in the app log? Also, did you restart the IS service after the change? Enough disk space where the logs are?Sukh

Please follow Sukh' suggestion to check for the event log, and paste the reatled information in your next post. Thanks, EvanEvan Liu TechNet Community Support

Dear, I am continuously facing events 2103, 958,2104,1036,1042 and 1047 in event log. Secondly when i create a new user in my ADS and in same wizard i create the account in server2 mailbox that is my exchange server. the wizard completed successfully but the it doesn't create User Email Account. Is there some setting to change in ADS for Exchange as in my old DC in ADS there was a tab of "Microsoft Exchange System Objects". but there is no such tab in new server ADS. Please help further. Regards, Rashid

It seems like you are having multiple issues. Focus on the on eyou have posted here regarding the DB dismount. Open a new post for the other. Can you actually post the event ID completly? Also, Run the ExchBPA (Health & Permissions) check.Sukh

Dear Sukh, yes i know there are multiple issues. but can you please just help me how can i make this exchange server as main exchange server. firstly i just want to create user mailboxes using this new server why i am unable to create mailbox of user by AD user and computers? :( regards, Rashid

Dear Sukh, Thanks for the help and by spending more time on research i have done with the mailboxes. I had to change the Exchange Server and Windows Domain Controller name in the recipient update service. cheers:) Regards, Rashid
